This is typical of a late 1918-1919 World War One Colt 1911. In order to meet production schedules for the war, Colt at the direction of the Army stopped applying their deep blue finish and went to a brushed finish that looked almost black. Hence the name "Black Army" for these pistols. The finish wore off almost as soon as the pistols were made. You will probably never see a "Black Army" 1911 that retains more then 85 to 90% of its original finish. I have a "Black Army" 1911 and shoot it now and then. They are great pistols that served our country for more then 60 years. Just be sure to add some high quality Tung or furniture oil to the wood grips now and then as it keeps them from drying out and cracking.
